This is causing the following error for me:

/home/sfrost/git/pg/dev/postgresql/src/backend/utils/adt/formatting.c: In function ‘DCH_to_char’:
/home/sfrost/git/pg/dev/postgresql/src/backend/utils/adt/formatting.c:2510:6: warning: format ‘%ld’ expects argument of
type‘long int’, but argument 3 has type ‘int’ [-Wformat=] 
      sprintf(s, ":%02ld", abs(tm->tm_gmtoff % SECS_PER_HOUR) / SECS_PER_MINUTE);
      ^

Since abs() is declared to return just an int.  I don't see it anywhere
in our tree and I'm not sure how portable it actually is, but labs() is
supposedly in C89, so perhaps that should be used here instead?

    Thanks!
